I choose a picture of the music building with the
lake in front, and the water falling. My original picture I think has a good
quality color , so I decide to change it to a black and white color. I changed
my color image to black and white by creating a new adjustment layer with
channel mixed to turn the image to black and white. Then I use visual Acuity to
make parts of my image to pop, I use this tool all around where the water is
falling to pop the original color (green) to create some contrast with the rest
of the lake and the picture.
